ing members may be limited by suitable buffers, as a in Figure 2 (omittedin Figure 1).

Each picking member is normally urged inwardly to the position shown in Figure 3, thus: A U-shaped frame a; is secured to and rocks with the shaft 0. Elongated springs 20 of the laminated-plate type are connected at'th'eir inner ends to studs m adjustable laterally in slots y in frame 0) and at their outer ends'overlie and bear upon the" respective arms m of the picker members; between its ends each spring is up ward y'opposedby an adjustable stop a, as a set screw, and in order to reduce somewhat the downward pressure of the spring on the picking member as the latter approaches its limit on each impulse imparted thereto by the spring there is an elastic cushion 2 on the frame of the loom underlying the free or o'uterend of the spring. The frame has bearings j for shaft 0, so as to prevent the latter from being bowed by the pressure of the springs.

For cocking and tripping the picking members inproper time there is the following mechanism characterized by-a ma ter lever from which both the cocking and tripping as to each pickingmember are effe'cted: Insuitablebearin'gs 3 on the frame y'yis journaleda rock shaft 41- equipped with a crank 5 which is connected by a pitinan 6 with a crank T'fiXGCl on a face plate 8 secured to a shaft 9 journaled in brackets 10 on one of the side frames, said shaft being con nected by spiral gearing 11 with a shaft 12 'journaled in the side frames and having gearing 13 connecting it with the crankshaft 5; the gearing 11and13 are such that theshaft 12 makes one revolution to two'of shaft Z), so as to obtain the actuation of each picking means (first one and then the other) on every other swing of the batten structure, Shaft 1 carries the aforesaid master leverl. To the upwardly projecting arm of this lever are pivoted the inner ends of two push rods 15 whose outer ends are supported by and slide in the loop studs m of the picking members and have shoul- The lowerders '15 to impinge the same. arm of thelever 1 1 has pivotally connected thereto links 16 the'outer ends of which are connected to the upwardly projecting arms of oscillators in the form of hell-crank levers 17 fulcrumed on studs 18 lined in the inner ends of the arms'k of the brackets is, the outwardlyprojecting arms of the levers 17 overlying the inner ends-of the cocking shoes and having adjustable devices, as set screws 19, to bear downwardly thereagainst. To obtain the pro'per timing of the cooking and tripping of the two picking members with respect to each other and with respect to the movements of the lay, suitable expeclients for adjustment are provided; Thus the studs 20 whereby the parts 6, 15 and 16 are connected to the oscillating structure including shaft 1-, crank 5 and lever 14 may be arranged in slots 21 (Figure 1) and the crank 7 may be adjustable with reference to the face-plate 6 around shaft 9 as an axis (see Figure 1 The structure last referred to rocks one way or the other on every back and forth movement of the batten and on each such movement through one push rod 15 (which .by its shoulder 15' impinges the loop stud m") it first cocks the corresponding pick- .ing member and then, through the opposite link 15 and lever 1'1",trips the other picking member by causing the corresponding cock" ing' shoe Q to be depressed against the tension of its spring. Thus the shuttle is shot back and forth across the lay, the picking member which it each time approaches being already fully pushed back for cooking by the time the shuttle reaches the picker appertaining thereto. The forward and back rocking of the batten structure (and with it the frame a and springs to and brackets is and the picking members and other parts carried thereby) on shaft 0 as an axis is possible with reference to' the structure 4- 5-1& on account of a certain amount of freedom of the parts incident to the appreciable length of the members 15, 16.

Referring, now, to the construction shown in Figures 7 to 12;

Th brackets 22 secured onthe ends of the Y alread described exce itin ithat the inner end of each horizontal arm 22' (corresponding to arm 70') of said bracket is eliminated and an inwardly projecting. arm 22" is provided on the web 22 thereof' The springs 25 for urging the picking members inwardly are secured to studs 26 on brackets attached tothe sidesof the loom, the springs projecting forwardly and having their ends arranged to pull downwardly on the arms 23 of the picking members through the medium of universal-joint connections or links 27 and having means, as set screws 28, for adjusting the pressure thereof.

The cooking and tripping of the picking members is accomplished in this case by a separate master lever 29 or oscillator for each picking member, the same being fulcrumed on the frame sides a and having its forward end projecting between the .roller 30 (on a stud 31 which projects from link 27) and the corresponding cocking shoe, there v the shoe 24 as it descends.

. The movements of the two levers 29 in proper time are efi'ected from sprocketw'heels33, which' have endless chains 34 ex; tending around them and sprocket wheels 35 on shaft "6, through pitmen 36 connecting ec-v levers.

In connection with this form of my invention I have illustrated means for preventing tripping of the picking members and therefore cutting out their operation when the means for stopping shaft 1) and hence the loom is operated. Here 37 indicates a part of the means for stopping the loom (which means-may be of any well known type), 37 here being a lever at one side of the loom, which, when thrown to the dotted position in Figure 7, to stop the loom, depresses a rod 38 which rocks a forklever 39 fulcrumed in the side frame,said fork-lever in turn shifting a lever 40, fulcrumed on arm 22", from between the lever centric points of sprocket-wheels 33 with the 1 29 and the cocking shoe; lever 40 has a spring elevated button 41 for transmitting the downward pressure of lever 29 to the cocking shoe, and when said 1ever40 is shifted 'to the dotted position (Figures 11 and 12)' lever 29 will fail to depress the cocking shoe, so that the picking member remains cocked. The two levers (one at each side of the loom) may be connected (Figure 11) so as both to be shifted and thus cut out both tripping members at the same time by the link 4-2. When the loom is turned over by hand there is a possibility of the shuttle leaving the lay and missing the box, on account of the forward movement of the lay being then too slow to keep the advancing lay against the shuttle should it tend for any reason to veer forward in its flight, and this creates an element of danger, especially since the shuttle travels at much greater velocity than in the ordinary case where it is' impelled by tappet means. action of the picking means when the -loomstopping means is operated will therefore be apparent.

The loose picker stick is an important feature of my invention because it permits its carrier or mounting (usually forced in the act of cooking slightly beyond'the cocking point) to re-act to the cocking point without afiecting the shuttle that has been driven into the corresponding box against the picker. The picking members and their actuating and cooking means and the means for releasing said members and re-cocking them are all formed and arranged so as to secure by- Letters Patentis i "-1.-In-"combination,' with a supporting The advantage of cutting out the obtain simplicity, durability and-efficiencyand avoid undue projection of parts.
